“Pets can be calming, and people may work better when there are pets around,” said Paula Fenton, who’s bringing her two huskies, Ajax and Sequoia, to work at The Pet Channel Network, a Web site with offices in Manhattan.

“They say you live longer if you have a pet,” Fenton said. “It lowers people’s heart rates. A pet gives you undying love. You can be as stupid as you want; there’s no judgment.”

Fenton said Ajax and Sequoia have been in the office before – and other employees occasionally bring in their dogs.

“They have fun, they play, people always pet them,” she said.

“They have their little treats. They’re dogs that are happy anywhere.”

The second annual Fido Friday is being promoted by Pets.com, a Web site that sells pet products.

“It’s an open call for people to bring their dog to work,” said Pets.com spokeswoman Sally Gibson.

She said the company sent information packs to about 3,000 people who requested them – with tips on how best to work dogs into the workplace.

The day starts with a benefit Bark Breakfast today from 7 to 10 a.m. at The Regency Hotel on Park Avenue.

Waiters will serve dogs scrambled eggs over rice at the sold-out chow-down – with money going to help FIDONYC, a shelter.

Stacy Landau plans to bring his white Maltese, Lucky, to the Regency breakfast and then to the office at Doggiewear Ltd., which makes dog coats and accessories and matching clothes for dog owners.

“They’re good company, friendly, they keep people happy,” Landau said of his animals. “It makes for a warm and friendly workplace. “
